Power management restrictions

As described in Power management, the system can
impose power restrictions on apps for a number of
reasons. The following table outlines the current restrictions. These restrictions do not
apply while the device is charging.

In each case, the most restrictive applicable setting is the one that takes
effect. For example, if Battery Saver is active and an app is in the Rare
bucket, the more stringent App Standby Buckets restrictions on FCM are applied.

Note: The values in this table are subject to change. These values are
given as examples, and improvements to the balance between battery life and timeliness of
content updates may cause them to change.

* If jobs restrictions are in force, the app is granted a window of ten
minutes at the specified interval. At the end of the ten minutes, all jobs are
postponed until the next window.

† If alarm restrictions are in force, all alarms will fire at the
scheduled window, and run for a maximum of 10 seconds.

‡ If network access is restricted, the app is granted a window of 10
minutes to use the network at the specified interval.

§ If high-priority FCM messages are capped, any messages after the cap is
reached are treated as normal-priority messages. FCM messages and their interactions with
App Standby Buckets are discussed in detail on the FCM
site.
